Today group A in Division 3 learned about the Marine Science Environment Protection (MSEP) Major at MMA. Before the class the other deckies and me thought anyone in MSEP were just another person out there trying to protect the whales and dolphins. But as the class progressed we realized the major involved a lot of cool topics like bathymetry (the study of the topography of the ocean) and oceanography. 
As our eyes were opened and minds immersed in all the cool stuff we realized that a lot of what MSEP covers is essential to the marine transportation major.

Towards the end of the day we got to do a really cool hands on activity which was the highlight of the day. We got to fire the XBT off the stern of the Kennedy. 

The XBT is a device that instantly sends back the temperature of the water as it dives deeper into the ocean abyss. After I personally fired the XBT, we walked back to the lab and saw the graph with live data. 
Overall everyone had a great time learning about the MSEP major and how important it is, thanks to the great leadership and training offered to us by the outstanding MSEP rates. Here is how it works.

There are times when we want to sample the water, but don’t want to take the time to stop the ship. One of the tools we turn to then is something called an Expendable Bathythermograph (XBT). Read more about this technology
